Need to identify an ECU

[projectxspeed]

Is there a way to tell by the numbers on the side of a USDM ecu to tell if its a manual or auot? I am looking at a getting a p28 from a yard, and I don't want them to give me an auto when I need a manual.

well I would if I could but the ecu has already been pulled. Its just chillin on a shelf; its hard to look at the car when its not there.

First, let's find out if we have an automatic, or a 5 speed ECU. If you don't want to plug it in and throw code 19 (automatic trans lockup solenoid) to find out it is an automatic ECU, then look at the code on the side. If the second to last number is a 5, then you have an automatic ECU (for OBD-1 USDM ECUs). If the 2nd to last # is anything but a five you have an ECU for a 5 speed. If you have a jdm obd-1 ecu, look at the last 3 digits: 900 or 901 will be an automatic.
